Clamping piece on bar contradicts the inner wall in pipeline, due to extension bar have it is multiple, therefore can holding in tube body of can stablizing of clamping piece
Wall realizes clamping of the clamping piece to tube body.
Since extension bar and clamping piece are that L shapes are less than multiple folders so multiple extension bars surround maximum diameter of a circle
Gripping member surrounds maximum diameter of a circle；The purpose of design be that will concentrate on clamping piece position to the chucking power to pipeline；If plus
Stock and clamping piece are integrally used to clamping tube body, then the stress surface of tube body by along the length direction of tube body have it is longer across
Degree, and due to the curvature of tube body itself or the precision of claw itself in reality processing, it is more difficult to realize that stock is equal with clamping piece
The effect being bonded completely with tube body is then susceptible at tube body one bar that is lengthened out and holds, and the tube body other side is clamped part and holds, and two
A bearing force is apart from each other on tube length direction, be easy to cause the torsion of tube body, and it is unstable in turn result in tube body chucking power
